DETAILED DESCRIPTION

The subject disclosure describes, among other things, illustrativeembodiments of systems and methods for providing accessibilityadjustments for one or more users via adjustments to content, such asvarious user input including user speech, images, and/or text, as wellas other content. The accessibility adjustments can be based on detectedor determined impairments (e.g., hearing, vision, speech, cognitive,motor skill, and so forth) and/or can be based on other factors, such asuser preferences. In one or more embodiments, user preferences andaccessibility requirements can be identified (e.g., in the Core Network)via accessibility profile tools. In other embodiments, media can bedynamically adapted to satisfy or address other issues, such asenvironmental conditions. In one or more embodiments, communicationsoccur between users and a multimedia accessibility platform (e.g., anapplication server in the core network, such as an IMS core network) canadapt content to meet user's desires. The adapted content can then beprovided to the end user device for presentation to the user as part ofthe communication session.

In one or more embodiments, the communication session can be monitoredto detect unclear words in user speech so that all or a portion of theunclear word can be adjusted so that the adjusted unclear word is clearto the intended recipient during the communication session. Theidentification of the unclear word can be performed utilizing speechrecognition. In one or more embodiments, user profiles can be accessedto facilitate the identification of unclear words, such as profileinformation indicating a user's propensity to drop syllables from theends of words or a user's accent. In one or more embodiments, categoriesof problematic words, sounds, letters, vowels, consonants and so forthfor a user can be identified in the user's profile to facilitatedetermining the unclear words. As an example, a user's profile canidentify that the user has a speech impairment resulting in a difficulttime pronouncing the letter “s.” This impairment information can be usedin conjunction with the speech recognition to identify unclear words inwhich the user was unable to sufficiently pronounce the “s” letter. Inone embodiment, libraries that are customized for speech impairments canbe accessed, such as a library that maps audio with a dropped syllableor with an unpronounced “s” letter to the corresponding word.

In one or more embodiments, adaptation functions can take intoconsideration network capabilities and device capabilities and/ornetwork conditions. In one or more embodiments, an API can be providedto expose functionality to 3rd party developers. In one or moreembodiments, the multimedia accessibility platform architecture can bebased on a USP platform. The adaptation functionality can be provided onits own, or in an existing application server (e.g., TAS or PS). Variousaccessibility adjustments can be performed including all or a portion ofan unclear word being replaced (e.g., by synthesized or recordedspeech); selective speech frequency amplification (e.g., a hearing aidin the cloud); speech to text conversion; speech to sign languageconversion; sign language to speech conversion; text adaptation (e.g.,enlargement, font change, color change and so forth); text to speechconversion; closed captioning; auditory amplification in the range ofmusic frequencies; color blindness adaptation; physical interfacingadaptation; epilepsy triggering prevention modifications (e.g., removalof selected stimuli from the content that is associated with an epilepsytrigger); input/output device capability enhancements; core networkintelligence considerations. In one or more embodiments, multipleadaptations can be performed for individuals on both the transmittingand receiving sides of a communication session or connection. Forexample, a user could be provided with speech amplification in additionto closed captioning.

FIG. 1 depicts an illustrative embodiment of a system 100 that canutilize a multimedia accessibility platform 110 (hereinafter server 110)to facilitate a communication session between a first end user 101utilizing an end user device 120 and a second end user 102 utilizinganother end user device 120. The end user devices 120 can be varioustypes of devices including smart phones, mobile devices, laptopcomputers, desktop computers, landline telephones, cordless telephones,set top boxes and/or any other communication device capable of engagingin a communication session to exchange or otherwise communicate voice,video and/or data. Platform 110 is described as a server, but it shouldbe understood that the platform 110 can be implemented using any numberof computing devices (e.g., a single server in a centralized system ormultiple server in a distributed environment), any type of computingdevices (e.g., a service provider server or a customer computingdevice), and/or any configuration of the computing device(s) (e.g., aserver farm where one or more servers are in a master/slave arrangementwith one or more other servers or a combination of service providerdevices and customer equipment performing the multimedia accessibilityplatform functions).

Server 110 can determine accessibility requirements or desires of one orboth the users 101, 102. Server 110 can execute various processingfunctions (e.g., text, audio, video and so forth) to implementaccessibility adaptation. The accessibility adaptation can includeadjustment of the multimedia content, adjusting the presentation of themultimedia content or otherwise making adjustments associated with thepresentation of the multimedia content to facilitate the accessibilityby the user to the content. In one or more embodiments, adjustments tothe content (e.g., user speech, music, graphics and so forth) can bemade and provided to the end user device in a timely manner as part ofthe communication session so that any conversation or communicationexchange is not disrupted.

As one example, the server 110 can monitor for and identify unclearwords during a communication session and replace all or a portion of theunclear word with audio content (e.g., synthesized and/or recordedspeech) as part of the communication session. The replacement of theunclear word or a portion thereof can be performed in a timely fashionso that the communication session is uninterrupted. Server 110 can alsouse a combination of adjusting a portion of an unclear word along withreplacing an entire unclear word. The identification of the unclear wordcan be based on speech recognition that can take advantage ofpersonalized libraries associated one or more of the users. In one ormore embodiments, previous communication sessions of a user can bemonitored and data can be collected to identify a propensity of the userto speak unclear words. For instance, speech impairment information canbe collected for a user that indicates words, syllables, letters and soforth that the user has difficulty pronouncing.

As another example, the server 110 can access one or more profilesassociated with one or more of the first user 101, the second user 102and/or one or both of the end user devices. These profiles can includevarious profile information and/or profiling tools associated withspeech, auditory, visual and/or cognitive information or data for theuser(s). In one or more embodiments, the server 110 can also access userpreferences for one or both of the first and second users so that thepreferences can be utilized in the accessibility adaptation.

Server 110 can address a number of different accessibility impairmentsor issues including mild hearing loss (e.g., via speech frequencyamplification), severe hearing loss (e.g., via speech to text or speechto sign language graphics), speech impairment (e.g., sign language tospeech or text to speech), mild vision impairment (e.g., via textadaptation), severe vision impairment (e.g., via text to speech), and/orcognitive disability (e.g., adjusting vocabulary). Server 110 can alsofacilitate the exchange of voice, video or data in a communicationssession in other ways such as by utilizing closed captioning, musicfrequency amplification, color blindness adaptation, physicalinterfacing adaptation, epilepsy triggering prevention modifications(e.g., via stimuli removal), addressing apraxia (motor planningdisorder, such as speech related), language translation for cognitivedisabilities (e.g. based on educational level, dyslexia, cerebral palsy,epilepsy, and so forth), and/or smart adaptation (e.g., devicelimitations, presentation environment, and so forth).

In one or more embodiments, the server 110 can determine a firstimpairment associated with first user 101 of first end user device 120,and can receive user input captured at second end user device 120 duringa communication session between the first and second end user devices.The server 110 can store instructions for executing a group ofadjustment techniques for modifying the user input, where the group ofadjustment techniques includes amplifying selective frequencies,translating the user input into sign language images, and/or modify allor a portion of an unclear word with audio content (e.g., synthesizedspeech or recorded speech). The server 110 can select an adjustmenttechnique from among the group of adjustment techniques. The server 110can adjust the user input according to the adjustment technique togenerate adjusted user input. The server 110 can provide the adjusteduser input to the first end user device 120 during the communicationsession.

In one or more embodiments, the server 110 can determine a degree ofimpairment for the first impairment, where the selecting of theadjustment technique from among the group of adjustment techniques isaccording to the degree of impairment for the first impairment. Theserver 110 can access an impairment profile for the first user 101,where the adjusting of the user input to generate the adjusted userinput is according to the impairment profile. The amplifying ofselective frequencies can be utilized for a first degree of impairment.The translating of the user input into sign language images can beutilized for a second degree of impairment, where the second degree ofimpairment is more severe than the first degree of impairment.

In one or more embodiments, the server 110 can include or otherwise bein communication with an application programming interface accessible bya remote device that is operated by a third party that is different froma service provider operating the server, where at least a portion of theinstructions for executing the group of adjustment techniques arereceived from the remote device.

In one or more embodiments, the server 110 can be an application serverof an IP multimedia subsystem network that facilitates combined servicesof circuit-switched and packet-switched systems, and can be incommunication with a serving call session control function and a mediaresource function of the IP multimedia subsystem network.

In one or more embodiments, the server 110 can determine a secondimpairment associated with the second user 102 of the second end userdevice 120 and can receive other user input captured at the first enduser device during the communication session. The server 110 can selectanother adjustment technique from among the group of adjustmenttechniques and can adjust the other user input according to theadjustment technique to generate adjusted other user input. The server110 can provide the adjusted other user input to the second end userdevice during the communication session.

In one or more embodiments, the server 110 can access an impairmentprofile for the first user 101, where the adjusting of the user input togenerate the adjusted user input is according to the impairment profile,where the impairment profile includes vision information for the firstuser, and where the group of adjustment techniques includes modifyinggraphics generated at the second end user device according to the visioninformation. The server 110 can obtain the vision information for thefirst user 101 by one of a vision test at a communication device (whichcan be the first end user device 120 or another device) of the firstuser prior to the communication session or receiving the visioninformation from a remote source operated by a third party that isdifferent from a service provider operating the system.

FIG. 2 depicts an illustrative embodiment of system 200 in which ahearing impairment, such as mild hearing loss, is detected and addressedvia accessibility adjustment. In one embodiment, the server 110 candetermine that the user 101 has a mild hearing loss such as viaaccessing information included in profile 210. The profile 210 can bevarious types of profiles such as a user profile that includes userpreferences, user impairments (e.g., in an impairment sub-profile forthe user 101), subscriber data, QoS data and so forth. In oneembodiment, the profile 210 can include audio diagnostic data for theuser 101, such as an audiogram 220 that provides data to indicate theuser's ability to hear, such as based on different frequencies,different intensity and so forth.

In one embodiment, the audiogram can be indicative of the user's hearingthresholds which are discovered by using behavioral hearing tests orphysiological tests, such as via audiometry. In one embodiment, thehearing test can be provided at the end user device 120 or at anothercommunication device of the user, can include different tones beingpresented at a specific frequency (pitch) and intensity (loudness), andthe user 101 can provide user input to indicate that he or she has heardthe sound. The lowest intensity sound that is heard can be recorded. Inanother embodiment, the audiogram can be obtained from a remote source,such as a medical provider of the user 101 or some other entity that isunaffiliated with the service provider operating the server 110.

In system 200, the server 110 can utilize the audiogram data toselectively amplify portions of speech of user 102 during thecommunication session. The server 110 can provide the adjusted userspeech to the end user device 120 of user 101 for presentation. Thetimeliness of the amplification and the providing of the adjustedcontent can enable the communication session to continue uninterrupted.As an example, certain frequencies identified in the audiogram as beingfrequencies that are difficult for the user 101 to hear, can beamplified by the server 110 and can be provided to the end user device120 of the user 101 to be presented as adjusted speech content. In oneor more embodiments, the implementation of selective frequencyamplification as an adjustment technique can be based on userpreferences, such as indicated in the profile 210, although in otherembodiments the use of selective frequency amplification can beinitiated based on other factors, such as user input at the beginning ofa communication session.

In one or more embodiments, the server 110 can store (locally and/orremotely) instructions for executing a group of adjustment techniquesfor modifying user input (e.g., user speech). The group of adjustmenttechniques can include amplifying selective frequencies, as well asother adjustment techniques such as translating the user input into signlanguage images or modifying all or a portion of unclear words withsynthesized or recorded speech. In one embodiment, the selection of theparticular technique among the group can be based on user preferences.In another embodiment, the selection of the technique from among thegroup of techniques can be based on a degree of user impairment. Forexample, the use of selective frequency amplification can be for a firstdegree of impairment and the translation into sign language images canbe for a second degree of impairment, where the second degree ofimpairment is more severe than the first degree of impairment. In oneembodiment, the amplification of selective frequencies can be performedin combination with identifying and modifying unclear words (in whole orin part) using synthesized or recorded speech.

FIG. 3 depicts an illustrative embodiment of system 300 in which ahearing impairment, such as a severe hearing loss, is detected andaddressed via accessibility adjustment. In one embodiment, the server110 can determine that the user 101 has a severe hearing loss such asvia accessing information included in the profile 210. In anotherembodiment, server 110 can determine that the user 101 has a preferencefor speech-to-text conversion such as via preferences identified in theprofile 210. In this embodiment, the server 110 can receive user speech325 captured at end user device 120 of second user 102. The server 110can apply speech recognition to the user speech 325 to generate text 350representative of the user speech which is then provided to end userdevice 120 of user 101 for presentation.

Various libraries can be utilized as part of the speech recognitionprocess, including natural language libraries. In one or moreembodiments, the libraries utilized for the speech recognition can beselected based on an identification of one or both of user 101, 102. Forinstance, user 102 can be identified as speaking with a particularaccent and a library corresponding to that accent can be utilized. Otherinformation, such as age, educational background, nationality,geographic location and so forth of one or both of the users 101, 102can be used as criteria in selecting libraries for generating the text350 via speech recognition.

In one or more embodiments, both the text 350 and the originalaudio-version of the user speech 325 can be provided to the end userdevice 120 of first user 101 for presentation. In another embodiment,the user speech 325 can be adjusted, such as selective frequencyamplification, and can be provided to the end user device 120 of firstuser 101, along with the text 350.

In one embodiment, the text 350 can be provided for all of the userspeech 325 or just a portion of the user speech. For instance, theserver 110 can identify a phrase that include frequencies that aredifficult for the user 101 to hear (e.g., via an audiogram for the user)and can translate the entire phrase. In another embodiment, if a phrasedoes not include a difficult frequency for the user to hear then theserver 110 can allow only the original user speech 325 to be provided tothe end user device 120 for that phrase.

FIG. 4 depicts an illustrative embodiment of system 400 in which ahearing impairment, such as a severe hearing loss, is detected andaddressed via accessibility adjustment. In one embodiment, the server110 can determine that the user 101 has a severe hearing loss such asvia accessing information included in the profile 210. In anotherembodiment, server 110 can determine that the user 101 has a preferencefor sign language images such as via preferences identified in theprofile 210. In this embodiment, the server 110 can receive user speech425 captured at end user device 120 of second user 102. The server 110can apply speech recognition to the user speech 425 to generate orotherwise obtain sign language images 450 that are representative of theuser speech and which are then provided to end user device 120 of user101 for presentation. In one embodiment, the server 110 can firsttranslate the user speech 425 into text, such as described in system300, and then can translate the text into sign language images 450(e.g., sign language images based on American Sign Language or otherforms of sign language).

The generation or obtaining of the sign language images 450 can be basedon various libraries or dictionaries, including libraries ordictionaries that are selected based on an identification of one or bothof users 101, 102. In one embodiment, one or more of the libraries ordictionaries can be personal libraries or dictionaries of one or both ofthe users 101, 102, such as libraries or dictionaries that are createdbased on one or more of monitoring communications of the user(s),preferences of the user(s), analyzing feedback from the user(s) and soforth. Other information, such as age, educational background,nationality and so forth of one or both of the users 101, 102 can beused as criteria in selecting libraries or dictionaries for generatingor obtaining the sign language images 450.

In one embodiment, the sign language images 450 can include an avatar475 that illustrates the sign language. The avatar 475 can be acomputer-generated graphical representation, such as of a person (e.g.,user 102), and/or can be recorded images of a person illustrating thesign language. The avatar 475 can be customized or otherwise adjustedbased on preferences of the user 101 and/or the user 102. For example,the user 101 may prefer an avatar that has an appearance similar to theappearance of user 102.

In one embodiment, the server 110 can detect a communication sessionbetween end user devices 120 of the first and second users 101, 102, andcan determine an impairment associated with the first user. The server110 can receive user speech 425 captured at the end user device 120 ofthe second user 102 during the communication session. Instructions forexecuting a group of adjustment techniques for modifying the user input425 can be accessed by the server 110, where the group of adjustmenttechniques includes translating the user speech into the sign languageimages 450, such as based on a degree of the impairment of the firstuser 101. In one embodiment, different adjustment techniques can beutilized for different degrees of impairment, such as amplifyingselective frequencies of the user speech 425 for a lesser degree ofimpairment. In this example, the server 110 can select a desiredadjustment technique from among the group of adjustment techniques suchas the sign language translation and can access a profile for the firstuser 101 (e.g., an impairment profile). The server 110 can adjust theuser speech 425 according to the selected adjustment technique (e.g.,sign language translation) and the impairment profile, and can providethe sign language images 450 to the end user device 120 of first user101 during the communication session. In one embodiment, the signlanguage images 450 can be provided to the end user device 120 of firstuser 101 along with the original user speech 425. In another embodiment,the sign language images 450 can be provided to the end user device 120of first user 101 along with a modified version of the original userspeech 425, such as selected frequency amplified speech and/or textconversion. In another embodiment, the sign language images 450 candepict the avatar 475 performing sign language as well as speaking theuser speech 425.

In one or more embodiments, the server 110 can modify or generatephysical characteristics of the avatar 475 based on user preferences,such as included in the profile 210. In one or more embodiments, theserver 110 can modify graphics based on changing size, color and/or fontof text. In one or more embodiments, the server 110 can access animpairment profile of user 101 that includes vision information for theuser, where the group of adjustment techniques includes modifyinggraphics generated at the other end user device according to the visioninformation, and where the server 110 obtains the vision information forthe user 101 by one of a vision test at a communication device of theuser 101 prior to the communication session or receiving the visioninformation from a remote source operated by a third party that isdifferent from a service provider operating the system.

In this embodiment, the server 110 canreceive graphics 725, such as SMS text message, entered at end userdevice 120 of second user 102. The server 110 can obtain impairmentinformation (e.g., via an impairment profile) associated with the user101. The server 110 can translate the captured graphics 725 based on theimpairment information to generate audio content 750 representative ofthe captured graphics. The audio content 750 can then be provided to theend user device 120 of user 101 for presentation. In one or moreembodiments, the audio content 750 can be generated based on synthesizedspeech. In other embodiments, the audio content 750 can be generatedusing recorded speech. Combinations of synthesized and recorded speechcan also be utilized. The synthesized or recorded speech 725 can beadjusted based on user preferences or other factors, such as gender ofvoice, pitch, intensity, accent and so forth. In one or moreembodiments, the audio content 750 can be provided to end user device120 of user 101 along with the original or a modified version of thegraphics 725 (e.g., an enlarged version of a text message).

FIG. 8 depicts an illustrative embodiment of system 800 in whichmultiple impairments are detected or otherwise determined. For example,a speech impairment of user 102 and a hearing impairment of user 101 canbe detected and addressed via accessibility adjustment. In oneembodiment, the server 110 can determine that the user 102 desires tocommunicate by sign language such as via accessing information includedin the profile 220. In one embodiment, the server 110 can determine thatthe user 101 desires to receive adjusted audio content such as viaaccessing information included in the profile 210. In this embodiment,the server 110 can receive sign language images 825 captured at end userdevice 120 of second user 102. The server 110 can apply imagerecognition to the sign language images 825 to generate or otherwiseobtain audio speech 850 that is representative of the sign languageimages. The audio speech 850 can be modified by server 110 based onimpairment information from the profile 210, such as an audiogram forthe user 101. For example, selected frequencies identified in theaudiogram can be amplified in the audio speech to generate an adjustedaudio speech which is provided to end user device 120 of user 101 forpresentation. In one embodiment, the server 110 can first translate thesign language images 825 into text, such as described in system 300, andthen can translate the text into audio content 850 which is then furthermodified based on the hearing impairment of user 101.

The translation of the sign language images 825 can be based on variouslibraries or dictionaries, including libraries or dictionaries that areselected based on an identification of one or both of users 101, 102. Inone embodiment, one or more of the libraries or dictionaries can bepersonal libraries or dictionaries of one or both of the users 101, 102,such as libraries or dictionaries that are created based on one or moreof monitoring communications of the user(s), preferences of the user(s),and so forth. Other information, such as age, educational background,nationality and so forth of one or both of the users 101, 102 can beused as criteria in selecting libraries or dictionaries for translatingthe sign language images 825 to the audio speech 850.

FIG. 9 depicts an illustrative embodiment of a communication system 900for providing a communication session that can deliver voice, videoand/or data, such as between users. In this embodiment, accessibilityadaptation can be performed within an IMS core network by way of anapplication server operating as server 110. However, the exemplaryembodiments also can include the server 110 operating in a network thatis not an IMS core network. In one or more embodiments, the server 110can be a separate device for providing multimedia accessibilityadjustments. In one embodiment, system 900 enables IMS originating andterminating filter criteria to invoke the accessibility adjustmentfunctionality of server 110 at session establishment.

Server 110 can be in communication with various components of the IMSnetwork such as an Home Subscriber Server (HSS), Serving Call SessionControl Function (S-CSCF), Media Resource Function (MRF) and so forth inorder to facilitate establishing the communication session, monitoringthe session and terminating the session. Server 110 can access profilesstored at storage devices 910 in the IMS network and can access tools920 that can facilitate analysis of the profiles, as well as adjustingthe multimedia content based on accessibility issues of the users.

In one or more embodiments, the system 900 can include an ApplicationProgramming Interface (API) 930 that is accessible by one or more remotedevices operated by one or more third parties that are different from aservice provider operating the system 900. In one or more embodiments,at least a portion of instructions for executing one or more adjustmenttechniques of the group of adjustment techniques can be received fromthe remote device (e.g., developed by third party developers that areindependent of the service provider operating the IMS core network).System 900 can communicate various information amongst its componentsusing various protocols, such as HTML5, XML, RTP, and so forth.

In one or more embodiments, the system 900 can generate or otherwiseobtain replacement audio content 975 that can be stored at a database orother storage device(s). In one embodiment, the replacement audiocontent can be generated by the server 110 from an end user device of auser and then stored in the database 975 for use in communicationsessions later for that user. For example, speech can be recorded at theend user device and identified as a clear word to be used in asubsequent communication session to replace an unclear word. In anotherexample, a third party can provide speech which is recorded and storedin the database 975 for subsequent use to replace all or a portion of anunclear word. In yet another example, speech can be digitally generatedincluding all or a portion of certain words (e.g., words that arefrequently mispronounced, words where syllables are frequently droppedand so forth).

FIG. 10 illustrates a method 1000 that can be performed by one or moreof the devices described in FIGS. 1-9 to provide accessibilityadjustments during a communication session. Method 1000 can begin at1002 where a communication session is detected, such as by anapplication server operating as server 110. At 1004, one or moreimpairments of one or both users can be detected or otherwisedetermined. The impairment can be identified based on various data, suchas from a profile(s) associated with one or both users, user inputentered at the time of the communication session, monitoring of previouscommunications associated with one or both of the users, user feedbackfrom prior communication sessions and so forth. At 1006, a degree of theimpairment can be determined such as from impairment information in theprofile.

At 1008, user input can be captured during the communication session.The user input can be user speech, sign language images of the user, orother content (e.g., text, graphics, music and so forth). At 1010, anadjustment technique can be selected for adjusting the user input. Inone embodiment, the adjustment technique can be selected from among agroup of adjustment techniques. In one embodiment, the selection can beaccording to the degree of the impairment. In one embodiment,instructions can be stored for executing the group of adjustmenttechniques for modifying the user input, where the group of adjustmenttechniques includes amplifying selective frequencies for a first degreeof impairment and translating the user input into sign language imagesfor a second degree of impairment, and where the second degree ofimpairment is more severe than the first degree of impairment.

At 1012, an impairment profile can be accessed for the user(s) for whomthe impairment was detected. At 1014, the user input can be adjustedaccording to the selected adjustment technique and the impairmentprofile to generate adjusted user input. At 1016, the adjusted userinput can be provided to the end user device during the communicationsession. The providing of the adjusted user input can be in place of theoriginal user input (e.g., replacing original user speech with modifieduser speech in which selected frequencies have been modified). In one ormore embodiments, the adjusted user input is being provided as part ofthe communication session in real-time or near real time or otherwisewithout a user-noticeable delay.

FIG. 11 illustrates a method 1100 that can be performed by one or moreof the devices described in FIGS. 1-9 to provide accessibilityadjustments during a communication session. Method 1100 can begin at1102 in which user speech is received by a system or device, such asserver 110. The user speech can be captured at a second end user deviceduring a communication session between the second end user device and afirst end user device. At 1104, speech recognition can be applied to theuser speech and at 1106 an unclear word in the user speech can beidentified based on the speech recognition.

Various libraries can be utilized as part of the speech recognitionprocess, including natural language libraries. In one or moreembodiments, the libraries utilized for the speech recognition can beselected based on an identification of one or more parties that areinvolved in the communication session. For instance, a user can beidentified as speaking with a particular accent and a librarycorresponding to that accent can be utilized. Other information, such asage, educational background, nationality, geographic location and soforth of one or more of the parties to the communication session can beused as criteria in selecting libraries for identifying words in theuser speech via speech recognition.

At 1108, the user speech can be adjusted to generate adjusted userspeech by replacing all or a portion of the unclear word withreplacement audio content. In one embodiment, only a portion of theunclear word (e.g., a dropped syllable at the end of the unclear word)is replaced with the audio content without replacing a remainder of theunclear word (e.g., the beginning portion of the word). At 1110, theadjusted user speech can be provided from the server 110 (or otherdevice(s) operating as the accessibility adjustment platform) to thefirst end user device during the communication session. The adjustmentof the unclear word can be performed in a timely manner so as to enablea smooth conversation between the users of the communication session. Inone embodiment, the adjusted unclear word is inserted into the stream ofaudio content without delay that is noticeable to the users.

In one or more embodiments, one or more steps of method 1000 can be usedwith one or more steps of method 1100 such as providing multipleadjustments to user speech including amplification of selectedfrequencies and replacement of all or a portion of unclear words withsynthesized or recorded speech.

In one or more embodiments, the replacement audio content can besynthesized speech, recorded speech or a combination thereof. In one ormore embodiments, the server 110 can access a speech profile for asecond user of the second end user device and can detect an undesirablespeech trait associated with the second user according to the speechprofile, where the speech recognition is applied to the user speechresponsive to the detecting of the undesirable speech trait.

In one or more embodiments, the server 110 can generate the speechprofile based on an analysis of one or more previous communicationsessions associated with the second user. In one or more embodiments,the server 110 can identify another unclear word in the user speechbased on the speech recognition, where the adjusting of the user speechto generate the adjusted user speech includes replacing the otherunclear word in its entirety with one of synthesized speech or recordedspeech. In one or more embodiments, the server 110 can access a speechprofile for a second user of the second end user device and can accessan impairment profile for a first user of the first end user device. Inthis example, the server 110 can detect at least one of an undesirablespeech trait associated with the second user according to the speechprofile or an impairment associated with the first user according to theimpairment profile, where the speech recognition is applied to the userspeech responsive to the detecting of at least one of the undesirablespeech trait or the impairment, and where the speech recognition is notapplied to the user speech responsive to the undesirable speech traitand the impairment not being detected. Continuing with this example, theadjusting of the user speech to generate the adjusted user speech caninclude amplifying selective frequencies of the user speech.

In one or more embodiments, the server 110 can access an impairmentprofile for a first user of the first end user device, where theimpairment profile includes an audiogram for the first user, and wherethe selective frequencies that are amplified are selected based on theaudiogram. Continuing with this example, a hearing test can be providedat a communication device (e.g., end user device 120) of the first userprior to the communication session and the audiogram can be generatedbased on the hearing test. In one or more embodiments, the audiogram canbe obtained from a remote source operated by a third party that isdifferent from a service provider operating the system. In one or moreembodiments, the user speech can be analyzed to generate undesirablespeech data, a speech profile for the second user can be accessed; andthe speech profile can be adjusted to indicate another undesirablespeech trait associated with the second user according to theundesirable speech data.

FIG. 12 depicts an illustrative embodiment of a communication system1200 for delivering media content and providing communication sessionswith accessibility adjustments. The communication system 1200 canrepresent an Internet Protocol Television (IPTV) media system.Communication system 1200 can be overlaid or operably coupled withsystems 100-900 as another representative embodiment of communicationsystem 1200. In one or more embodiments, system 1200 enables dynamicallyreplacing all or a portion of one or more identified unclear words in acommunication session with replacement audio content such as synthesizedor recorded speech.

In one or more embodiments, system 1200 enables determining a firstimpairment associated with a first user of a first end user device andreceiving user input captured at a second end user device during acommunication session between the first and second end user devices.System 1200 enables storing instructions for executing a group ofadjustment techniques for modifying the user input, where the group ofadjustment techniques includes amplifying selective frequencies andtranslating the user input into sign language images. System 1200enables selecting an adjustment technique from among the group ofadjustment techniques, adjusting the user input according to theadjustment technique to generate adjusted user input, and providing theadjusted user input to the first end user device during thecommunication session. Various components of system 1200 will bedescribed herein that can perform all or a portion of the accessibilityadjustments of the exemplary embodiments, including the steps of method1000.

The IPTV media system can include a super head-end office (SHO) 1210with at least one super headend office server (SHS) 1211 which receivesmedia content from satellite and/or terrestrial communication systems.In the present context, media content can represent, for example, audiocontent, moving image content such as 2D or 3D videos, video games,virtual reality content, still image content, and combinations thereof.The SHS server 1211 can forward packets associated with the mediacontent to one or more video head-end servers (VHS) 1214 via a networkof video head-end offices (VHO) 1212 according to a multicastcommunication protocol.

The VHS 1214 can distribute multimedia broadcast content via an accessnetwork 1218 to commercial and/or residential buildings 1202 housing agateway 1204 (such as a residential or commercial gateway). The accessnetwork 1218 can represent a group of digital subscriber line accessmultiplexers (DSLAMs) located in a central office or a service areainterface that provide broadband services over fiber optical links orcopper twisted pairs 1219 to buildings 1202. The gateway 1204 can usecommunication technology to distribute broadcast signals to mediaprocessors 1206 such as Set-Top Boxes (STBs) which in turn presentbroadcast channels to media devices 1208 such as computers or televisionsets managed in some instances by a media controller 1207 (such as aninfrared or RF remote controller).

The gateway 1204, the media processors 1206, and media devices 1208 canutilize tethered communication technologies (such as coaxial, powerlineor phone line wiring) or can operate over a wireless access protocolsuch as Wireless Fidelity (WiFi), Bluetooth, Zigbee, or other present ornext generation local or personal area wireless network technologies. Byway of these interfaces, unicast communications can also be invokedbetween the media processors 1206 and subsystems of the IPTV mediasystem for services such as video-on-demand (VoD), browsing anelectronic programming guide (EPG), or other infrastructure services.

A satellite broadcast television system 1229 can be used in the mediasystem of FIG. 12. The satellite broadcast television system can beoverlaid, operably coupled with, or replace the IPTV system as anotherrepresentative embodiment of communication system 1200. In thisembodiment, signals transmitted by a satellite 1215 that include mediacontent can be received by a satellite dish receiver 1231 coupled to thebuilding 1202. Modulated signals received by the satellite dish receiver1231 can be transferred to the media processors 1206 for demodulating,decoding, encoding, and/or distributing broadcast channels to the mediadevices 1208. The media processors 1206 can be equipped with a broadbandport to an Internet Service Provider (ISP) network 1232 to enableinteractive services such as VoD and EPG as described above.

In yet another embodiment, an analog or digital cable broadcastdistribution system such as cable TV system 1233 can be overlaid,operably coupled with, or replace the IPTV system and/or the satelliteTV system as another representative embodiment of communication system1200. In this embodiment, the cable TV system 1233 can also provideInternet, telephony, and interactive media services.

The subject disclosure can apply to other present or next generationover-the-air and/or landline media content services system.

Some of the network elements of the IPTV media system can be coupled toone or more computing devices 1230, a portion of which can operate as aweb server for providing web portal services over the ISP network 1232to wireline media devices 1208 or wireless communication devices 1216.

Communication system 1200 can also provide for all or a portion of thecomputing devices 1230 to function as a multimedia accessibilityplatform (herein referred to as server 1230), including performing allor a portion of the functions of server 110 described with respect tosystems 100-900. The server 1230 can use computing and communicationtechnology to perform function 1262, which can include among otherthings, identifying one or more impairments associated with one or moreusers for a communication session, obtaining impairment informationassociated with the identified impairment(s), selecting an appropriateadjustment technique for captured or otherwise obtained content,adjusting the content (e.g., user speech, sign language images, text,graphics and so forth) based on the selected adjustment technique andthe impairment information. The media processors 1206 and wirelesscommunication devices 1216 can be provisioned with software functions1264 to utilize the services of server 1230, such as providingimpairment information, requesting an accessibility adjustment,performing an impairment test (e.g., an audio test to generate anaudiogram), pre-processing of the captured content, processing some ofthe accessibility adjustment functions of method 1000 to create adistributed processing environment with the server 1230, and so forth.

FIG. 13 depicts an illustrative embodiment of a communication system1300 employing an IP Multimedia Subsystem (IMS) network architecture tofacilitate the combined services of circuit-switched and packet-switchedsystems. Communication system 1300 can be overlaid or operably coupledwith systems 100-900 and communication system 1200 as anotherrepresentative embodiment of communication system 1300.

System 1300 enables receiving user speech captured at a second end userdevice during a communication session between the second end user deviceand a first end user device, accessing a second profile for a seconduser of the second end user device, and accessing a first profile for afirst user of the first end user device. The system 1300 enablesdetecting at least one of an undesirable speech trait associated withthe second user according to the second profile or an impairmentassociated with the first user according to the first profile. Thesystem 1300 enables applying speech recognition to the user speechresponsive to the detecting of at least one of the undesirable speechtrait or the impairment and enables identifying an unclear word in theuser speech based on the speech recognition. The system 1300 enablesadjusting the user speech to generate adjusted user speech by replacingat least a portion of the unclear word with replacement audio contentand providing the adjusted user speech to the first end user deviceduring the communication session.

System 1300 enables end user devices to: provide impairment information,such as to an application server, receive adjusted user input as part ofa communication session, and/or present the adjusted user input. Theadjusted user input can be generated (e.g., by the application server)from a modification of user input captured at one of the end userdevices during the communication session, where the modification isresponsive to a detection of an impairment of a user. The adjusted userinput can be based on an adjustment technique selected (e.g., by theapplication server) from among a group of adjustment techniques.Instructions for executing the group of adjustment techniques can bestored or otherwise be accessible (e.g., to the application server),where the group of adjustment techniques can include amplifyingselective frequencies, converting speech to text, and/or translatinguser input into sign language images.

Communication system 1300 can comprise an HSS 1340, a tElephone NUmberMapping (ENUM) server 1330, and other network elements of an IMS network1350. The IMS network 1350 can establish communications betweenIMS-compliant communication devices (CDs) 1301, 1302, Public SwitchedTelephone Network (PSTN) CDs 1303, 1305, and combinations thereof by wayof a Media Gateway Control Function (MGCF) 1320 coupled to a PSTNnetwork 1360. The MGCF 1320 need not be used when a communicationsession involves IMS CD to IMS CD communications. A communicationsession involving at least one PSTN CD may utilize the MGCF 1320.

IMS CDs 1301, 1302 can register with the IMS network 1350 by contactinga Proxy Call Session Control Function (P-CSCF) which communicates withan interrogating CSCF (I-CSCF), which in turn, communicates with aS-CSCF to register the CDs with the HSS 1340. To initiate acommunication session between CDs, an originating IMS CD 1301 can submita Session Initiation Protocol (SIP INVITE) message to an originatingP-CSCF 1304 which communicates with a corresponding originating S-CSCF1306. The originating S-CSCF 1306 can submit the SIP INVITE message toone or more application servers (ASs) 1317 that can provide a variety ofservices to IMS subscribers.

For example, the application servers 1317 can be used to performoriginating call feature treatment functions on the calling party numberreceived by the originating S-CSCF 1306 in the SIP INVITE message.Originating treatment functions can include determining whether thecalling party number has international calling services, call IDblocking, calling name blocking, 7-digit dialing, and/or is requestingspecial telephony features (e.g., *72 forward calls, *73 cancel callforwarding, *67 for caller ID blocking, and so on). Based on initialfilter criteria (iFCs) in a subscriber profile associated with a CD, oneor more application servers may be invoked to provide various calloriginating feature services.

Additionally, the originating S-CSCF 1306 can submit queries to the ENUMsystem 1330 to translate an E.164 telephone number in the SIP INVITEmessage to a SIP Uniform Resource Identifier (URI) if the terminatingcommunication device is IMS-compliant. The SIP URI can be used by anInterrogating CSCF (I-CSCF) 1307 to submit a query to the HSS 1340 toidentify a terminating S-CSCF 1314 associated with a terminating IMS CDsuch as reference 1302. Once identified, the I-CSCF 1307 can submit theSIP INVITE message to the terminating S-CSCF 1314. The terminatingS-CSCF 1314 can then identify a terminating P-CSCF 1316 associated withthe terminating CD 1302. The P-CSCF 1316 may then signal the CD 1302 toestablish Voice over Internet Protocol (VoIP) communication services,thereby enabling the calling and called parties to engage in voiceand/or data communications. Based on the iFCs in the subscriber profile,one or more application servers may be invoked to provide various callterminating feature services, such as call forwarding, do not disturb,music tones, simultaneous ringing, sequential ringing, etc.

In some instances the aforementioned communication process issymmetrical. Accordingly, the terms “originating” and “terminating” inFIG. 13 may be interchangeable. It is further noted that communicationsystem 1300 can be adapted to support video conferencing. In addition,communication system 1300 can be adapted to provide the IMS CDs 1301,1302 with the multimedia and Internet services of communication system1200 of FIG. 12.

If the terminating communication device is instead a PSTN CD such as CD1303 or CD 1305 (in instances where the cellular phone only supportscircuit-switched voice communications), the ENUM system 1330 can respondwith an unsuccessful address resolution which can cause the originatingS-CSCF 1306 to forward the call to the MGCF 1320 via a Breakout GatewayControl Function (BGCF) 1319. The MGCF 1320 can then initiate the callto the terminating PSTN CD over the PSTN network 1360 to enable thecalling and called parties to engage in voice and/or datacommunications.

It is further appreciated that the CDs of FIG. 13 can operate aswireline or wireless devices. For example, the CDs of FIG. 13 can becommunicatively coupled to a cellular base station 1321, a femtocell, aWiFi router, a Digital Enhanced Cordless Telecommunications (DECT) baseunit, or another suitable wireless access unit to establishcommunications with the IMS network 1350 of FIG. 13. The cellular accessbase station 1321 can operate according to common wireless accessprotocols such as GSM, CDMA, TDMA, UMTS, WiMax, SDR, LTE, and so on.Other present and next generation wireless network technologies can beused by one or more embodiments of the subject disclosure. Accordingly,multiple wireline and wireless communication technologies can be used bythe CDs of FIG. 13.

Cellular phones supporting LTE can support packet-switched voice andpacket-switched data communications and thus may operate asIMS-compliant mobile devices. In this embodiment, the cellular basestation 1321 may communicate directly with the IMS network 1350 as shownby the arrow connecting the cellular base station 1321 and the P-CSCF1316.

It is further understood that alternative forms of a CSCF can operate ina device, system, component, or other form of centralized or distributedhardware and/or software. Indeed, a respective CSCF may be embodied as arespective CSCF system having one or more computers or servers, eithercentralized or distributed, where each computer or server may beconfigured to perform or provide, in whole or in part, any method, step,or functionality described herein in accordance with a respective CSCF.Likewise, other functions, servers and computers described herein,including but not limited to, the HSS, the ENUM server, the BGCF, andthe MGCF, can be embodied in a respective system having one or morecomputers or servers, either centralized or distributed, where eachcomputer or server may be configured to perform or provide, in whole orin part, any method, step, or functionality described herein inaccordance with a respective function, server, or computer.

In one or more embodiments, the server 1230 of FIG. 12 can be operablycoupled to the communication system 1300 for purposes similar to thosedescribed above. Server 1230 can perform functions 462 and therebyprovide accessibility adjustment services to the CDs 1301, 1302, 1303and 1305 of FIG. 13. CDs 1301, 1302, 1303 and 1305, which can be adaptedwith software to perform functions 464 to utilize the services of theserver 1230 and/or the application server 1317. In other embodiments,server 1230 can be an integral part of the application server(s) 1317performing functions 462. In one embodiment, server 1230 and applicationserver 1317 can perform a distributed environment for performing theaccessibility adjustments.

For illustration purposes only, the terms S-CSCF, P-CSCF, I-CSCF, and soon, can be server devices, but may be referred to in the subjectdisclosure without the word “server.” It is also understood that anyform of a CSCF server can operate in a device, system, component, orother form of centralized or distributed hardware and software. It isfurther noted that these terms and other terms such as DIAMETER commandsare terms can include features, methodologies, and/or fields that may bedescribed in whole or in part by standards bodies such as 3rd GenerationPartnership Project (3GPP).

In addition, the controller 1406 can be adaptedin various embodiments to perform the functions 462 and 464 in order tofacilitate accessibility adjustments.

Upon reviewing the aforementioned embodiments, it would be evident to anartisan with ordinary skill in the art that said embodiments can bemodified, reduced, or enhanced without departing from the scope of theclaims described below. For example, the accessibility adjustments canbe performed for more than two users involved in a communicationsession. As an example, a conference call amongst three or more users atthree or more different end user devices can result in various userinput adjustments being made and delivered to the respective user basedon an impairment of that user. For instance, the first user may desireselective frequency amplification of user speech, the second user maydesire a speech-to-text conversion, and the third user may desire aspeech-to-sign language conversion. In this example, the server 110 (orother device performing the accessibility adjustment) would performmultiple adjustments on the same user input to satisfy the desires ofthe recipients.

In another embodiment, there may be multiple users utilizing a singlefirst end user device that is in a communication with a second end userdevice. In this example, the server 110 (or other device performing theaccessibility adjustment) would determine the adjustments to be madewhich would satisfy the desires of the multiple users at the singledevice. For example, if one of the first users has a mild hearingimpairment and another of the users has a severe hearing impairment thenthe server may select a speech-to-text conversion of the user speech. Inother embodiments, multiple conversions can be performed to satisfy bothimpairments, such as delivering both adapted user speech (e.g.,amplifying selected frequencies based on an audiogram) and sign languageimages to the single first end user device.

In one or more embodiments, the conversion of the user input (e.g., userspeech) may not be verbatim. For instance, words or phrases can bechanged based on a number of factors, such as education level of therecipient. In another embodiment, certain words may be changed toaccount for other impairments, such as trying to avoid certain wordsbased on detecting a recipient user that has dyslexia.

In one or more embodiments, the user input can be content that isobtained from another source rather than captured at the device. Forexample, a first user may download and transmit a color image to asecond user where colors can be modified in color image by server 110 toaccount for a detected color blindness of the second user.

In one or more embodiments, cognitive impairments can be addressed. Asan example, a user with limited reading ability (e.g., in a developingcountry) may rent or otherwise temporarily obtain a cell phone. The usermay speak his or her name, which is recognized and authenticated. Theuser may be provided with an icon based interface that minimizes readingdependency. The user's personal Enhanced Address Book (EAB) can bedownloaded from server 110 to the end user device. The user can seeimages of friends, their communication capabilities, and/or socialpresence information of the user's contacts (e.g., RCS functionality).The user can tap on a video icon by a friend's image, and a video callcan be established. In this embodiment, iconography can be implementedby the server 110 to facilitate the communication session based on adetected or determined cognitive impairment of the user. Otheraccessibility adjustments can also be performed including languagetranslations.

In one or more embodiments, end user devices can be automaticallyprovisioned (e.g., at the time of purchase of the device) withinformation and software to make use of the accessibility adjustmentfunctionality of server 110. Other embodiments can be used in thesubject disclosure.
